A.
B.
C.
D.
Decreased pressure.
Addition of water.
Increased depth in Earth’s interior.
Increased temperature.
Explanation:
It is true that temperature increases with depth, but so does
pressure. Increased pressure raises the melting point of rock,
preventing rock at depth from melting.

A.
B.
C.

describe the rock that forms from molten lava. Therefore, lava is
extrusive.

The main producer of sediment is
A.
B.
C.
D.
biological weathering.
ice wedging.
chemical weathering.
physical weathering.
Explanation:
Most rock is rendered to sediment by chemical reactions that
cause the rock to decompose. Chemical weathering is a rotting
process, just like the rotting of meat. The main difference is that
chemical weathering occurs via inorganic reactions, whereas the
rotting of meat is an organic process.

How is erosion different from weathering?
A.
B.
C.
D.
Erosion is the process of removing sediment from weathered rock.
Erosion produces more sediment than weathering.
Erosion produces less sediment than weathering.
Erosion and weathering are different ways of saying the same thing.

the movement of rock and sediment through the hydrologic cycle.
Explanation:
B and C describe individual aspects of the rock cycle. The only
part of the hydrologic cycle capable of moving sediment (only one
part of the rock cycle) is surface flow in liquid water or ice.
